2 Claims.

The invention relates to new and useful improvements in a mounting for a sewing machine whereby said machine is resiliently supported free from direct contact with the table carrying the same.

An object of the invention is to provide a mounting for a sewing machine whereby said machine may be placed in an opening formed through the table therefor and resiliently supported from the table with the machine free from contact with the table.

A further object of the invention is to provide a mounting for a sewing machine. of the above character wherein the bed plate on which the sewing machine is mounted is resiliently supported beneath the table.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawing- Figure 1 is a View partly in section and partly in side elevation showing a mounting for a sewing machine embodying the invention, and

Fig. 2 is a plan view of the table and supporting means for the sewing machine, with the bed of the sewing machine indicated in broken lines.

The invention has to do with a mounting for a sewing machine. In certain types of work, it is desirable to mount the sewing machine so that the work support is near the upper face of the supporting table on which the machine is mounted. To this end, the table is provided with an opening extending all the way through the table, and beneath said opening is a supporting bed plate to which the sewing machine bed proper is xedly attached. The opening is so dimensioned that the sewing machine is entirely free from contact with the side walls of the opening. 'I'his supporting bed plate is suspended beneath the table by resilient devices carried by the table. Each device is in the form of a bolt which extends through a rubber block or resilient member placed in the socket in the table. The bolt extends down through the table and is free from contact therewith, and at its lower end it is xedly connected to and suspends the supporting bed plate for the machine.

Referring more in detail to the drawing, the sewing machine is indicated diagrammatically at 1. Said sewing machine is provided with a work support 2 mounted on the bed 3 of the sewing machine. The sewing machine is supported on a table 4. The table has an opening 5 therethrough which is dimensioned so that the bed of the machine and the parts between the bed and the work support 2 are free fromy contact with the side walls of the opening, so that any vibration,

laterally or vertically, in the sewing machine incident to the operating parts thereof, will not be imparted to the sewing machine table. Located beneath the sewing machine table is a supportingV bed plate 6. This bed plate is considerably larger than the opening 5 through the table and extends beyond the opening at the sides and ends thereof. The sewing machine bed 3 is secured to this sup- G5 ,porting bed plate by threaded bolts 7, '7. As

shown, there are three Vof these bolts.

The supporting bed plate 6 is suspended beneath the table by hangers, each of which includes a resilient element. These hangers are all similar in construction, and a description of one will answer for the others. Each hanger includes a bolt which extends centrally through a rubber block 9. There isa cap 1'0 at the bottom of the block which encloses the lower end portion thereof and a cap 11 which encloses the upper end of the block. These caps are of metal. The bolt 8 is provided with a relatively flat, thin, extended head 12' which overlies the rubber block bearing against the cap 11. This rubber block so with the caps provide a resilient unit' forfsuspending the bed plate 6.v The resilient unit forms no part of the present invention per se,but is shown, described` and claimed in the application of Charles S. Thompson Serial No. 596,- 831, filed March 4, 1932. A The work supporting table is provided with a socket or recess which receives this resilient unit, and the unit bears against thel bottom wall of the recess. There is an opening 13 centrally of 90 the recess through which the bolt 8 extends, and this opening is so dimensioned that the boltl is out of contact with the walls thereof. The bolt 8 passes through the bed plate, and a nut 14 threaded on to the bolt before the bed plate 95 is placed thereon serves as a limiting stop, and the nut l5 clamps the bed plate against -the nut 14. This firmly secures the bed plate 6 'to the bolts, and the bolts are supported solely by the resilient units carried by the table. The resilient unit substantially lls the socket or recess in which it is placed, and has little or no lateral movement therein, and therefore, any lateral vibrations in the sewing machine imparted to the bedplate 6 will be absorbed by the resilient 105 units and not imparted to the table. Likewise. any vertical vibrations `in the sewing machine incident to the movement of its parts will be absorbed by the resilient units.

It will be apparent that a mounting has been provided for a sewing machine wherein the machine is resiliently supported in the opening in the table without any direct contact between the sewing machine and the table. 'I'he work support 2, as shown, is a slight distance above the upper face of the table 4. A tray or board 16 is shown as applied to the table` so as to be ilush with the work support to facilitate the handling of the material being stitched.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

I- Iaving thus described the invention, what I claim as new and desire tol secure by Letters Patent, is-

1. The combination of a sewing machine, a

supporting table therefor having an opening,

therethrough in which the sewing machine is adapted to be placed, a supporting bed plate beneath the table on which said machine is ilxedly mounted, hangers for suspendingthe bed plate. each hanger including a bolt rigidiyattached to the supporting bed plate and extending through the table, a resilient member carried by the table surrounding said bolt and supporting the same.

2. The combination of a sewing machine, a supporting table therefor having an opening therethrough in which the sewing machine is adapted to be placed, a supporting bed plate beneath the table projecting on its sides and ends beyond the opening and on which said machine is iixedly mounted, a plurality of hangers for suspending the bed plate from said table, each hanger including a bolt fixed to the bed plate and extending through the table, said bolt having a head at its upper end, said table having a socket therein, and a resilient memberilocated 1n said socket through which said bolt extends, with the head thereof contacting with the upper face of the resilient member.
